• Chemische Eigenschaften

  Drak-Purple Solid

• Verwenden

  Carotenoid pigment found mostly in animal organisms, but also occuring in plants; thought to be the precursor of astacin. Animal studies indicate that it reduces blood glucose and ameliorates several parameters of the diabetic metabolic syndrome. It improves blood flow and vascular tone in models of hypertension.

• Verwenden

  astaxanthin is an anti-oxidant. Molecularly, astaxanthin is similar to beta-carotene, but in clinical studies it appears to demonstrate stronger anti-oxidant properties, including an ability to inhibit lipid peroxidation and an anti-inflammatory capacity. It is used in cosmetics for its anti-oxidant properties, and for possible uV protection abilities. Astaxanthin is a naturally occurring pigment, part of the carotenoid group, and found in many foods. It is what provides salmon and certain crustaceans (e.g., shrimp, crab, lobster) with their reddish tint. Astaxanthin can also be synthetically produced.

• Verwenden

  Astaxanthin is a carotenoid pigment found primarily in marine animals including shrimp and salmon. It is a potent lipid-soluble antioxidant.

• Definition

  ChEBI: Astaxanthin is a carotenone that consists of beta,beta-carotene-4,4'-dione bearing two hydroxy substituents at positions 3 and 3' (the 3S,3'S diastereomer). A carotenoid pigment found mainly in animals (crustaceans, echinoderms) but also occurring in plants. It can occur free (as a red pigment), as an ester, or as a blue, brown or green chromoprotein. It has a role as an anticoagulant, an antioxidant, a food colouring, a plant metabolite and an animal metabolite. It is a carotenone and a carotenol. It derives from a hydride of a beta-carotene.

• Biotechnologische Produktion

  Commercial production processes are known in which astaxanthin production is performed in closed photobioreactors by Cyanotech Corporation (Hawaii). This mode of cultivation strongly improves process control, algae predation, and production, but the fermentation costs are significantly higher. These higher costs have to be compensated by high productivity levels and more efficient downstream processing in order to make a competitive product.
  Most of the astaxanthin available on the world market has been produced chemically since the 1950s, for example, by DSM and BASF, and the process is efficient and cost-effective. There are also microbial sources, for example, X. dendrorhous (previously described as P. rhodozyma), and the alga H. pluvialis. X. dendrorhous has been widely investigated as to its potential of astaxanthin production for salmonids. This has resulted in a race between companies in the 1980s and 1990s. Natural astaxanthin is currently available as a spray-dried powder (5–10 mg astaxanthin/g), and is supplemented to fish feed to give salmonid flesh its pink color. Another astaxanthin application is in the nutraceutical market, as astaxanthin is regarded as a potential antioxidant. With regard to production by algae, H. pluvialis is the only species commercially cultivated for astaxanthin production. This green alga is able to grow under autotrophic, heterotrophic, and mixotrophic conditions. An example of the latter is its ability to grow in the presence of acetate and light. Astaxanthin accumulates in response to stress in lipid globules of the cells.

• Allgemeine Beschreibung

  all-trans-Astaxanthin is a ketocarotenoid, most commonly identified in marine and aquatic animals, including krill, wild salmon, rainbow trout, microalgae, shells of lobster, shrimp, seafood products, etc. It is biologically known as a vitamin A precursor, and exhibits strong antioxidant property, much higher compared to vitamin E and β-carotene. Its role in food and the medicinal industry is also well-defined.

• Biochem/physiol Actions

  Astaxanthin is a potent carotenoid antioxidant found in marine algae, red yeast and many other plant and animal sources. Animal studies indicate that it reduces blood glucose and ameliorates several parameters of the diabetic metabolic syndrome. It improves blood flow and vascular tone in models of hypertension. In vitro studies indicate that it upregulates connexin 43 and thus, may be chemopreventive against cancer.
